Embodiment 1

[0070] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Take running on a computer terminal as an example, such as figure 1 As shown, the computer terminal may include one or more (only one is shown in the figure) processors 101 (the processors 101 may include but not limited to processing devices such as microprocessor MCU or programmable logic device FPGA, etc.), for storing Data storage 103, and transmission means 105 for communication functions. Those of ordinary skill in the art can understand that, figure 1 The shown structure is only for illustration, and it does not limit the structure of the above-mentioned electronic device.

[0071] The above-mentioned terminals may be SDN equipment and OTN equipment.

[0072] The memory 103 can be used to store software programs and modules of application software, such as program instructions / modules corresponding ...

Embodiment approach 1

[0183] Assume that link 1 fails and 80 services recover successfully in parallel, for example Figure 11 Shown:

[0184] In step S1101, the controller senses that the link 1 is interrupted (that is, the transmission plane fails) through the alarm information reported by the device side. According to the location of the fault, it is judged that 80 ODU0 services need to be restored at the same time. Path calculation is performed on 80 services, and the recovery paths of the 80 services are all from point A (link 5) to point D (link 4) to point B.

[0185] Step S1102, analyze the recovery paths of 80 services, convert the routing information into SNC cross information, and classify the SNCs according to the operating device side nodes, specifically convert the routing information of each service into multiple SNC cross information, and then convert Operate multiple SNC cross information at point A, point D, and point B to analyze and synthesize separately, and finally generate ...

Embodiment approach 2

[0193] Assuming that link 1 fails, due to the failure of crossover execution of nodes on the device side, some of the 80 services are successfully restored, and some of them fail. The flow chart of this embodiment is as follows Figure 12 shown.

[0194] In step S1201, the controller perceives that the link 1 is interrupted (that is, the transmission plane fails) through the alarm information reported by the device side. According to the location of the fault, it is judged that 80 ODU0 services need to be restored at the same time. Path calculation is performed on 80 services, and the recovery paths of the 80 services are all from point A (link 5) to point D (link 4) to point B.

[0195] Step S1202, analyzing the restoration paths of 80 services, converting the routing information into SNC cross information, and classifying the SNCs according to the operating device side nodes, specifically converting the routing information of each service into multiple SNC cross information...

Abstract

The invention provides a multi-service parallel recovery method, device and system under SDN architecture, wherein the method comprises the steps of: receiving one or more pieces of fault warning information reported by OTN network equipment belonging to an OTN node; generating a corresponding configuration message for the OTN node based on the received fault warning information, wherein the configuration message is used for reconfiguring all fault services on the OTN node; and sending the configuration message to the corresponding OTN node. By means of the multi-service parallel recovery method, device and system under the SDN architecture provided by the invention, the technical problem that the routing fault processing efficiency in an SDN is relatively low in a related technology can be solved.

Description

technical field [0001] The present invention relates to the Internet field, in particular, to a multi-service parallel recovery method, device and system under the SDN architecture. Background technique [0002] With the rapid development of SDN network technology, international standard organizations such as OIF and ONF, which are committed to formulating OTN network-related standards and architectures, have also shifted their research focus to SDN. Therefore, the evolution of traditional OTN networks to SDN architectures has become a general trend. With the development of network flattening, the OTN network and the PTN network will gradually merge, and more and more small-grained services will be connected to the OTN network for transmission. However, due to the high transmission bandwidth of the OTN network, the interruption of one optical cable will cause dozens or even hundreds of services to be re-routed. [0003] "Recovery" refers to rerouting and establishing a new ...
